The Ugra class was the NATO reporting name for a group of submarine tenders built for the Soviet Navy in the late 1960s. The Soviet designation was Project 1886. One extra ship the INS Amba was built for the Indian Navy to a modified design. The ships were intended to provide afloat support, including supplies, water, torpedoes, fuel, and battery charging; minimal repair facilities. Often employed as flagships/command ships for submarine squadrons

Two ships were completed to a modified (Project 1886U, Russian: 1886У) design as training ships. They were named Borodino (launched 30 January 1970, commissioned 16 January 1971) and Gangut (launched 30 December 1970, commissioned 10 October 1971)[1] and they were also scrapped in the late 1990s.
